Safety measurements done to determine the safety profile of the treatment; safety parameters included adverse events, biochemistry, hematology, vital signs and performance status.

Adverse events are recorded according to CTCAE v5.0 (CTCAE grade 2-5 rate)

Detailed Description

Three parallel cohort, multicenter, open-label, phase I/II clinical trial to analyze the safety and feasibility of PD-1 inhibition with Nivolumab given concomitantly with standard radiotherapy regimens in the treatment of esophageal cancer.

Cohort A: Advanced/inoperable esophageal cancer, eligible for palliative radiotherapy of the primary tumor.

Cohort B: Inoperable esophageal cancer without metastases, eligible for definitive chemoradiotherapy Cohort C: Operable esophageal cancer eligible for neoadjuvant chemoradiotherapy

Inclusion Criteria

Age > 18 years

Specific inclusion criteria - Cohort A: 1. Eligible for palliative fractionated radiotherapy of the esophageal- or gastroesophageal cancer as determined by the multidisciplinary team (MDT) meeting. 2. Expected survival >3 months. 3. Not bulky disease, i.e. palliative radiotherapy towards the primary tumor is intended to palliate dysphagia and/or pain and systemic treatment could be delayed to AFTER protocol therapy if possible.

Specific inclusion criteria – Cohort B: 1. Eligible for definitive chemoradiation of localized but inoperable esophageal- or gastroesophageal cancer as determined by the multidisciplinary team (MDT) meeting. 2. Regional disease, i.e. no metastasis outside the radiation field (PTV). 3. Considered candidate/ able to adhere to the intended chemoradiotherapy

Specific inclusion criteria – Cohort C: 1. Eligible for neoadjuvant chemoradiotherapy and surgery of the esophageal- or gastroesophageal cancer as determined by the multidisciplinary team (MDT) meeting. 2. Regional disease, i.e. no metastasis outside the radiation field (PTV). 3. Considered candidate and able to adhere to the intended neoadjuvant chemoradiotherapy and planned surgery.

Patients should have previously untreated histologically proven squamous cell carcinoma or adenocarcinoma of the esophagus or the gastroesophageal junction (GEJ), Siewert I, II or III

Must be ambulatory with a performance status ECOG 0 or 1

Adequate organ function based on clinical examiniation and lab values as defined in the below: Absolute neutrophil count: ≥ 1,5 x109/L Platelets: ≥ 100 x109/L Hemoglobin: ≥ 9 x109/L Creatinine ≤ 1,5 upper limit normal (ULN) OR measured/calculaterd GFR≥60 mL/min Albumin ≥ 30 g/L Total bilirubin ≤ 1,5 ULN ASAT and ALAT ≤ 2,5 ULN, or ≤ 5 ULN for subjects with liver mets. International Normalized Ratio (INR) ≤ 1,5 ULN and Activated Partial Thromboplastin Time (TT) ≤ 1,5 ULN unless subject is receiving anticoagulant therapy. Such therapy (if indicated) should be converted to adequate therapy with low-molecular weight heparin such as Dalteparin before chemotherapy or treatment with IMP.

Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 28 days prior to the start of study drug (screening phase). Women must not be breastfeeding.

WOCBP should use highly effective adequate method to avoid pregnancy for 23 weeks (30 days plus the time required for Nivolumab to undergo five half-lives) after the last dose of investigational drug. Adequate methods are described in Appendix I.

Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception during the study treatment period and until 7 months after last dose of Nivolumab

Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH GCP, and national/local regulations.

If Dysphagia score >2, a nasogastric feeding tube should be inserted during the aid of gastroscopy, and nasogastric tube feeding started before radiotherapy.

Exclusion Criteria

Previous treatment with radiotherapy towards volumes within the thoracic cavity

History of prior malignancy within the last 5 years, excluding curatively treated basal cell or squamous cell carcinoma of the skin.

Any reason why, in the opinion of the investigator, the patient should not participate.

Previous treatment with any PD-1 or PD-L1/2 inhibitor

Hypersensitivity to the investigational product or any of the drug formula contents

Esophageal stenting

T4b if infiltration into the aorta or the trachea

History of prior autoimmune disorders requiring systemic therapy (excluding Insulin or Thyroid replacement therapy)
